* elf-bfd.h (struct got_entry, struct plt_entry): Forward declare.

Browse Source 
(struct elf_link_hash_entry): Add "glist" and "plist" fields to
	"got" union, and declare as gotplt_union.  Use gotplt_uinion for
	"plt" field.
	(struct elf_link_hash_table): Make "init_refcount" a gotplt_union.
	Add "init_offset" field.
	(struct elf_obj_tdata <local_got>): Add "struct got_entry **" to union.
	(elf_local_got_ents): Declare.
	* elf.c (_bfd_elf_link_hash_newfunc): Adjust initialization of "got"
	and "plt".
	(_bfd_elf_link_hash_hide_symbol): Use "init_offset".
	(_bfd_elf_link_hash_table_init): Set "init_offset".
	* elflink.h (NAME(bfd_elf,size_dynamic_sections)): Set init_refcount
	from init_offset.
	(elf_adjust_dynamic_symbol): Set plt and got offsets using init_offset.

	* elf.c (bfd_elf_local_sym_name): Split out from..
	(group_signature): ..here.
	* elf-bfd.h (bfd_elf_local_sym_name): Declare.
